LAMP BURNER.

Application filed. October 26, 1922. Serial No. 597,108.

To all whom it may concern."

Be it known that we, (1) PETER PRYTULA and (2) CONSTANTINE KoRoL, citizens of the Dominion of Canada, residing at Ratner, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Lamp Burners, of which the following is a specification.

This invention relates to certain new and useful improvements in lamp burners, and has particular reference to the provision of a shutter or a similar device for extinguishing the flame whenever desired.

The primary object of the invention resides in the provision of a shutter associated with the wick tube of a lamp burner that normally occupies a position laterally of the tube and is adapted to be movedto a position overlying the upper end of the tube for the purpose of extinguishing the flame of the burner wick.

lVith the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevational view of a lamp burner constructed in accordance with the present invention, the wick flame extin uishin device )ivotallv connected I b b .1 thereto, 7

Figure 2 IS a bottom plan view of the burner,

Figure 3 is a top plan view of the burner with the hinged cover removed, showing the pivotally mounted shutter arranged adjacent the wick tube,

Figure 4 is a vertical cross sectional view of the burner showing the tensioned pivotally.111ounted shutter and the wick feeding spur wheels associated with the wick tube, and further showing by dotted lines, the shutter overlying the upper end of the wick tube,

Figure 5 is a bottom plan view similar to Figure 2, showing the operating mechanism shifted to a position for moving the shutter to a position overlying the wick tube,

Figure 6 is an enlarged fragmentary detail sectional view, showing a portion of the shaft supporting the wick feeding spur wheels, and

Figure 7 is a detail sectional on line VII-VII of Figure 6.

In the accompanying drawing, which-- View, taken the perforated plate 2, while the usual resilient chimney supporting arms 6 are as sociated with the base flange 1. A wick tube 7 extends through the casing 4 and'perforated plate 2 with the upper end thereof alined with the slot in the cover 5. As shown more clearly in Figs. 2, 5 and 6. a shaft 8 is journaled transversely of the casing 4, and has fixed thereto a plurality of spur wheels 9 which project through openings formed in the adjacent side of the wick tube 7 for engagement with a wick for raising and lowering the same in an obvious manner by rotation of the shaft 8.

The flame extinguishing device is asso ciated with the upper end of the wick tube 7 including a shaft 10 journaled in the casing 4 and parallel with the shaft 8 carrying the wick feeding spur Wheels 9, one projecting end of shaft 10 havin a gear wheel 11 fixed thereto as shown in *igs. 2 and 5. A shutter in the form of an angle arm has the vertical leg 12 thereof secured at its lower I end to the shaftlO at a point spaced slightly outwardly of the adjacent end of the wick tube 7, the arm or leg 12 projecting upwardly through a slotted opening 13 formed in the perforated disk plate 2, and carrying upon the upper end thereof an angularly directed arm 14 constituting the shutter for extinguishing the wick flame. The shutter arm 14 is normally retained in a position laterally of the open upper end of the wick tube 7 by a spring 15 secured at one end to the shutter arm 14, and at its other end to the perforated disk plate 2 as clearly shown in Figs. 3 and 4.

The operating mechanism for shifting the shutter arm 4 will move the same to a position overlying the open upper end of the wick tube 7 and is associated with the shaft 8, the detail construction thereof being shown more clearly in Fig. 6 wherein the outer end of the shaft 8 is shown polygonal in cross section as at 8 with a rotating button 16 secured to the outer end thereof. A sleeve 17 having a rectangular bore is slidably mounted upon the polygonal end 8 of the shaft 8 and carries upon the inner end thereof a pinion 18, While radial arms 19 diametrically project from the outer end of the sleeve 17 at a point spaced inwardly of the disk button 16. A U-shaped strap 20 has the side legs thereof freely extending through openings formed in the disk button 16 with the inner projecting ends thereof secured to the radial arms 19. To maintain the sleeve 17 at its limits of outward movement relative to the shaft end 8, a coil spring 21 surrounds the shaft engaging at one end the pinion l8 and at its other end the washer 22 positioned adjacent the casing 4, as clearly shown in Fig. 6.

In the normal position of the operating mechanism, the pinion 18 is laterally off et with respect to the gear 11 upon the shaft 10, as shown in Fig. 2, and when so positioned, the shaft 8 is rotated by the disk button 16 for raising and lowerin wick within the tube 7 by the spur wheels 9 projecting into the tube as shown in Fig. 5, the spring 15 normally holding the shutter arm 14 latcrally positioned with respect to the open upper end of the wick tube 7 as shown in Figs. 8 and 4. When it is desired to extinguish the wick flame, the U-shaped strap 20 is pushed inwardly relative to the disk button 16, shifting the sleeve 17 upon the polygonal end 8 of the rod or shaft 8 against the tension of the spring 21, to move the pinion 18 into meshing engagement with the gear wheel 11,'rotation of the shaft 8 at this time effecting rotation of the shaft 10 to move the shutter arm ltagainstthe tension of the spring 15 to aposition overlying the open upper end of the wick tube 7 for eX- tinguishing the wick flame as will at once be obvious. Nhen pressure is relieved upon the disk button 16, the spring 21 will force the sleeve 17 outwardly to disengage the pinion 18 from the gear 11 while the spring 15 moves the shutter arm M from a position overlying the open upper end of the tube 17, to the full line position shown in Figs. 3 and 4;.

Vi hile there is herein shown and described the preferred embodiment of the present invention, itis nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed as new is 1. In a flame extinguisher for lamp burners, wherein a burner is provided with a wick tube, and a shaft carrying spur wheels projecting into the wick tube, a sleeve slidably mounted on sa-idshaft, a pinion carried by said sleeve, a second shaft journaled paralled with the first named shaft, a gear wheel fixed thereto, and a shutter carried by said shaft and having the upper end thereof positioned overlying the open upper end of the wick tube and adapted to be so moved when the pinion and gear are in mesh.

2. In a flame extinguisher for lamp burners, wherein a burner isprov-ided with a wick tube, and a shaft supporting spur wheels extending into the wick tube, a shaft journaled parallel with the first named shaft, a shutter fixed to said shaft, a gear fixed to one end of the last named shaft, a tension'ed sleeve slidably mounted on the wick feeding shaft and rotatable therewith, a pinion secured to the inner end of said sleeve and normally out of mesh with the gear, and means for moving said sleeve against the tension thereof tocause meshing engagement between the pinion and gear to effect movement of the shutter for disposing the same over the open upperend of tlie wick tube.

In testimony whereof we afiix our signatures.
